Description
Technical field
The preparation method that the present invention relates to a kind of adsorbent, belongs to water-treatment technology field, and the oil removing being suitable to oil-polluted water purifies, particularly to the preparation method of a kind of endecatylene amido propyl betaine modification infusorial earth and the application in water processes thereof.
Background technology
Developing rapidly along with China is industrialized, the demand of oil is increasing, and the use of the oil product more next moon is extensive, creates substantial amounts of containing sewage. Oily waste water is mainly derived from the processes such as the oil recovery of petroleum industry, oil refining, store oil, transport and petrochemical industry production, after oil product enters water body, moisture film can be formed on top layer, stop oxygen to dissolve in water body, thus causing water hypoxia, biological death, causing serious environmental pollution. The rules and regulations such as " People's Republic of China's law of marine environmental protection " that current China promulgates, the highest permission concentration of emission of oily waste water is 10mg/L. So, the multiple fields of petrochemical industry and environmental conservation etc. instantly that the are treated as problem demanding prompt solution of oily waste water. Absorption method is the one in numerous process technique, and absorption method is processed the research of oily waste water and focuses mostly at the adsorption efficiency improving adsorbent by the many scholars of recent domestic, probes into the method for modifying etc. of adsorbent. The features such as it is simple that its absorption method has technique, and adsorption rate is high, applied widely, stable in properties are used widely in sewage disposal. Adsorbent for oily waste water absorption has activated carbon, expanded graphite, modified alta-mud, modified coal ash, serpentine, attapulgite, zeolite etc. Gao Sainan etc. have studied oil extraction waste water biological treatment water outlet charcoal test, (high match man etc. oil extraction waste water biological treatment water outlet charcoal test is studied. Environmental science and technology, 2010-12,33 (12): 56 65); Wang Shuzhao etc. have studied the expanded graphite absorption property to oily waste water, (Wang Shuzhao etc. the expanded graphite Study on adsorption properties to oily waste water. scientific and technical innovation Leader .2012 (22): 7-8);Shu Ming is brave etc. have studied modified alta-mud and processes the test of emulsifying liquid waste water, and Shu Ming is brave. and modified alta-mud processes the experimental study of emulsifying liquid waste water. Chemical Engineer, 2012 (8): 34-38); Deng Hui etc. have studied flyash and remove the application of oily waste water, (China such as Deng Hui utilizes flyash to remove the applied research of oily waste water. flyash, and 2012 (3): 10-14).
Shortage of resources and environmental pollution have become as two big subject matters of the world today; therefore; utilize natural resources; develop feasible, green economy, environmentally friendly product and technology will become the inexorable trend of sustainable development; China can be strengthened and tackle the strained handling ability of sudden severe contamination event; to environmental conservation, maintain ecological balance, safeguard social safety and stably have a very important role. Diatom is a kind of single celled algae, individual only small, is generally 1 ��m to several millimeters. When, after this water plant death, remains can deposit in lake in ocean, forms kieselguhr. Kieselguhr mineralogically belongs to opal structural, and its chemical composition is mainly silicon dioxide, containing a small amount of aluminium oxide, ferrum oxide, calcium oxide, magnesium oxide, potassium oxide, sodium oxide and organic matter. The advantageous properties such as kieselguhr is a kind of porous, density is little, specific surface area is big, excellent adsorption, high temperature resistant, insulation, are therefore widely used in the industrial circles such as chemical industry, oil, building materials, food. But, the application of some special absorption is higher to diatomaceous quality and performance requirement, though and China's diatomite ore aboundresources, but quality is general not high so that it is application in many aspects is restricted. Therefore, diatomaceous purification, the modified important means being to improve kieselguhr application. The application adopts endecatylene amido propyl betaine that kieselguhr carries out chemical modification to prepare during the material of a kind of oil suction processes for the water of sewage, develop diatomaceous new application.
Endecatylene amido propyl betaine, pale yellow transparent thick liquid, soluble in water, having excellent performance, extremely low irritating amphoteric surfactant, this product is a kind of bifunctional compound, containing alkyl functional group and amido functionality, there is excellent oil absorbency. The material modified with endecatylene amido propyl betaine has very strong lipophile, is good oil absorption material.
Through retrieval, have no the preparation method using endecatylene amido propyl betaine modification infusorial earth, and apply it to the absorption report of oil in sewage disposal.
